We are planning to add the following to the definition of "label":

    [STD13] permits labels to contain arbitrary binary data that might
    not represent text.  IDNA does not apply to non-text labels.
    Throughout this document the term "label" is shorthand for "text
    label", and "every label" means "every text label".

Does that help?

Yes, we are removing all ASCII code points from the Nameprep prohibited
list.
